In this paper we examine kinematic evidence for the existence of rotating planes. We compare the kinematic results we obtain from selection criteria modelled after that of I14 to simple numerical models of satellite behavior. The structure of the paper is as follows: In Section \ref{sec:data} we discuss the selection of the observational sample and the presense of the co-rotation signal. In Section \ref{sec:models} we introduce our numerical models and compare the mock observations derived from the models to the true observational data. In Section \ref{sec:discuss} we discuss our results in the context of the search for M31-like planes elsewhere in the Universe. Throughout our analysis, we employ a $\Lambda$ cold dark  matter ($\Lambda$CDM) cosmology with WMAP7+BAO+H0 parameters  $\Omega_{\Lambda} = 0.73$, $\Omega_{m} = 0.27$, and $h =0.70$ \cite{Komatsu_2011}, and unless otherwise noted all logarithms are base 10.
